Florin 'Postulate' - John of Heinsberg

John of Heinsberg held the Prince-Bishopric of Liège for thirty-six years, an unusually long tenure that coincided with the general consolidation of Flemish and Mosan gold coinage under Burgundian commercial pressure. The "Postulate" designation in the coin's name refers to his initial status upon appointment — he was postulated rather than formally elected, meaning the cathedral chapter bypassed canonical election procedures and submitted the appointment directly to papal confirmation, a distinction that mattered enormously in ecclesiastical politics and was apparently worth commemorating in the coinage itself.
